What may have been a carefully scheduled therapeutic tennis tournament is suddenly a Grand Slam event that Russian tennis hottie Maria Sharapova can win. Sharapova may be recuperating from right shoulder surgery, but she still has an overpowering will to win that overrides the rust of her extended layoff.

The rust was evident in the first set against Kazakh star Yaroslava Shvedova. Maria over-hit ground strokes, flailed at serves and often seemed out of place with long strides better suited for grass than with the shorter, quicker moves needed for clay.

After a 1-6 thumping in set one, Maria came out firing in set two. She broke in game 5 and rode the break to a 6-3 reversal squaring the match. Suddenly, Sharapova had Yaorslava on the run from side to side and pinned deep behind the baseline.

To her credit, Yaroslava hung on. In a match with serious repercussions for a berth in the semis, Shvedova used an effective two-handed backhand down the line to stave off the grunting Grand Slam winner and former number one.

Sharapova’s shoulder remains a concern. Her usually reliable first serve was missing today at Roland Garros. The Russian star double faulted 11 times. That statistic is cause for concern and not typical of Grand Slam semifinalists.

Maria found a way to compensate for her service woes. By controlling the tempo and the court noise, Maria set herself firmly in control of play. From the start of set two, Maria struck 26 outright winners. Additionally, her ability to move Yaroslava around the court took a toll on the Kazakh’s serve.

By the end of the match, Yaroslava’s first serve was clocked at a mere 90 mph. As the match began to slip away, Yaroslava seemed to become tentative. Maria broke to go up 5-4 in set three.

After faulting the first serve of the key 10th game, Sharapova took a moment to gather herself. Her focus became clear. Suddenly, this match was all about the leggy blonde and her ability to put contenders away. She promptly rattled off four winners and the match was finished.

Many of the big names are experiencing first set tremors. Venus never recovered from hers. Elena Dementieva won when Jelena Dokic retired. The competition only gets better from here. Round four winners can ill afford to come out flat. It would bee unlike Maria to make the same mistake twice. Today was another good mental exercise for a shining star the tour could use.
